This upgrade is required to be in-line with: NVIDIA/cudf#9716

Depends on: rapidsai/integration#390

I guess this won't pass until CI version of clang-format is upgraded.

Yes Mark, that's correct. The CI changes rapidsai/integration#390 have been merged but will likely take some time for new images to be out
